I really enjoy Jasper Fforde's Thursday Next mysteries, so I decided to give this one a go, but it wasn't nearly as good as the Thursday books, so I was a little disappointed. This author generally writes for adults, although there's no reason a younger audience couldn't read them, I just don't think they'd want to read them. They're pretty literary, with references to all kinds of novels and storylines, which can make them a little confusing if you don't have enough background knowledge. I think that may have been part of my problem with this one. Th storyline in this novel revolves around the NCD, the Nursery Crimes Division, so you need to know a lot of nursery rhymes, and although I have a passing knowledge of many, I don't have a thorough knowledge of them, which really might have helped.
Based on the title, The Big Over Easy, can you figure out which nursery rhyme was the heart of this novel? If you guessed Humpty Dumpty, who had a great fall, you'd be right. Humpty is dead, and it's up to detectives Jack Sprat (who, surprise, surprise, cuts off all the fat from his bacon) and Mary Mary to figure out what happened. And each time they think they've got it, they discover they're not quite there yet.
This book is an ok read, but if you're just trying Jasper Fforde, go for the Thursday next books. The Eyre Affair is the first in the series I think.
